Can't get video capture card to work

I bought a "H.32x PCI" video capture card off of ebay and installed it. It kept crashing whenever I tried to capture video, but I did get it to work once. Does anyone know what I should do or where I can get windows me drivers?

Uhm.....certain codecs can produce problems....divx can crash things, so can angel potion (because they are hacked versions of other codecs aparently), not often but sometimes.....also (and it may only be my system) running *any* other program at the same time greatly increases the chance of a crash.
